Thus, the umbrella facet of the umbrella not only could be unfold completely, the supporting force is increasing, but also the volume of the folded umbrella largely being reduced which becomes convenient for bringing.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to a kind of automatically unfold-and-fold structure of the folded umbrella, especially refers to a kind of automatically unfold-and-fold structure of the folded umbrella which could shrink the folded umbrella volume of the umbrella body so that it is more convenient for bringing the umbrella.

[0003] 2. Description of the Prior Art

[0004] Right now, the automatically umbrella appears on market is only supported by one spring on unfolding and there is no consideration that said spring is settled beside the shaft inside the

[0005] umbrella or inside the shaft of the umbrella which supporting force is insufficient so that the lower portion of the umbrella could not be unfolded to a proper position or it is easily to be influenced by the winds on unfolding which impairs the effect of shielding. Besides, since the support force of the spring of the automatically folded-typed umbrella is insufficient, the shaft inside the umbrella could only be made with 2-3 segments to uncooperative with stretch-and-shrink; on the other hand, when the facet of the umbrella is unfolded, there must is suitable shielding facet, so there must is a certain length for the length of the shaft in each segment of the umbrella which caused too long of the length after the umbrella is tighten up and is inconvenient in bringing. Recently, people setting a structure with a sliding wheel and the pull-string inside the shaft of the umbrella to solve the defect that the lower portion of the umbrella couldn't be unfolded into the proper position due to insufficiency of the support force of the spring wherein one end of the pull-string is connecting to the fixed pedal on lower portion of the umbrella and another end is connecting to the lower portion of the umbrella bypass the sliding wheel so when the user is unfolding the umbrella, the lower portion is extending upwardly and the lower portion is being pulled upwardly so that the lower portion reaches the fixed position; although this structure makes the umbrella unfold completely; however, since the volume of the umbrella is quite large and inconvenience for bringing, and there is no function of automatically folding the umbrella for such umbrella.

[0006] From this we know that there still is many drawbacks for the above-mentioned traditional object which is not a fine design and requires to be bettered.

[0007] The inventor of this invention thinks to better and innovate it due to each drawback derived from the above-mentioned traditional umbrella and studied for many years and he finally succeeded in complete researching the automatically unfold-and-fold structure of the folded umbrella of this invention.

SUMMARY OF THE INVENTION
